REWINDING MECHANISM FOB TALKINGr-MACHINES.

y Application filed June 16,

7 '0 all whom it may concem:

Be it known that I, NIcALo MIoUocI, a subject of the King of Italy, residing at Philadelphia, in the county ofPhiladelphia i and' State of Pennsylvania, have invented new and useful' Improvements inRewinding Mechanism for Talking-lachines, of which the following is a specificaton.

This invention relates to talking machines and it has for its main object to provide a talking machine the motive mechanism whereof, is pedal operated, that is to say', the driving mechanism can be wound up by foot power.

A further object of my invention is to provide means whereby the motive mechanism is prevented from being accidentally overwound. u

The invention also includes other novel objects and features of Construction and ar angement hereinafter more definitely speci- `With the above objects in view, the nature of which will more fully appear as the description proceeds, the invention consists essentially in the novel Construction, combination and arrangement of parts as herein fully described, illustrated, and particularly pointed out b the appended claim.

In the furt er disclosure of the invention, reference is to be had to the accompanying sheets of explanatory drawings, constituting a part of this specification, in which similar characters of reference denote correspondin parts in all the Views; and in which,-

. %figure l is a front elevation of a talking machine embodying my improvements.

Fig. 2 is a side elevation of the same with parts broken away or in section to show the underlying structure. I

Fig. 3 is an enlarged detail sectional elevation of the pedal mechanism.

Fig. 4 is a front elevation to an enlarged scale of the motor for Operating the Inachine; and

Fig. 5 is a side, elevationof the same looking to the left hand of Fig. 1.

Fig. 6 is a detail section showing the Slippage clutch.

Figs. 7 and 8 are detail views of the roller clutches.

Referring more particularly to the views, the numeral 10, designates a talking ma` chine cabinet which comprises an upper part Specfication of Letters Patent.

11, in which is located the motive mechanism, an intermediate or storage section 12,

for the reception of the records, and a lower part 13, in which is located the pedal mechanism designated generally by the numeral 14, the entire cabinet being mounted on ball casters 15, whereby said cabinet can be easily moved about from place to'place. r

Referring more particularly to Figs. 4, 5, the motive mechanism comprises a spring winding drum 16, having a gear 17, meshing with a pinion 18, mounted on a shaft 19, said shaft carrying a second gear 20 in gear with a pinion 21 carried by a shaft 22. This shaft 22 hassecured thereto a toothed wheel 23, in gear with the governor-mechanism 24,

and it is to be noted that all of the foregoing parts are constructed and arranged in accordance with thewell known methods of i arranging a spring motor.

In accordance wi'h my invention I mount a shaft 25, adjacent the above described mechanism and key or otherwise secure thereon a gear-wheel 26, in` mesh with a pinion 27, mounted on a shaft 29, that carries the record supporting platform and I wish to here point out that the shaft 29, is mounted in a removable bearing 31.

Supported by a depending bracket or framework 32, beneath the mechanism above described, is a vertical shaft comprising upper and lower parts 33, 34, respectively, said parts being connected aXially in line with one another by a slippage clutch 35, and the upper plart 33, has associated therewith a 'roller clutch 36 for preventing back motion.

Keyed or otherwise connected to the lower part 34, is a bevel wheel 37, in gear with a i bevel wheel 38, on a horizontal shaft 39,

imounted in bearings 40, 40, integral with the framework 32. This shaft 39 has mounted thereon, roller clutches 41, 41, to which are attached crank members or levers 42, to the i can be draWn ontwardly from the lowersecton of the cabinet or retracted thereinto as desred.

The slppage clntch 35 includes clntch members 59 and 60, one of saidmembers being Secured to the adjacent ends of the upper and lower parts 33 and 34 of the vertical shaft. The member 59 carres a band (31 which encircles the member 60, being adustably Secured to the member ojas indicated at 62. The band 61 may thns be` tensioned so as to bindnpon the memberfiO and in the ordinary operation of rewinding, Will cause the npper and low-er parte 33 and 34 of the vertical shaft to rotate together;

The band 61 is so tensioned however, that When the spring motor` has become smiliciently Wound the said npper and lower parts 33 and 34 otthe vertical shaft will be cep-able of relative movement and damage to the spring motor Will thns be prevented. The roller clutch 36 comprises members ,62 and 63, the former* being` provided with a cam clntch64 within which a roller 65 operates. The action of this roller will grip and cause the members 62 and-63 to rotate in unison when the shaft revolves in one direction, but Will permit of independent movement between the members' 62 and 63 When the shaft is rotated'n an opposite direction. The roller clntches 41 are smlar in construction to the roller clutch 36 ;nst

described except, that they may be provided With a pluralityof camnotches 66' With1n which operate the rollers 67. The action of the clntches 44 s to grpthe shaft 39 When the pedals are operated tecanse the levers to move in one direction, but to release said shaft when the lever is moved in anop poste direction. This causes the shaft 39 to be revolved in one direction only.

In 'order to providea simple means for controlling the speed of the machineI eX- tend the governor shaft 53, somewhat and monnt thereon a lever 54', which is connected by a link 55, to a handle or indieator element 56 adapted to pass over an appropriate indicator 57 mounted on the front of the machine. e

From the foregoing it Will be readily seen that by my invention I provide an eX- tremely simple and eflfective pedal operated .clntch connecting said sections,- a' second shaft disposed at right angles to` the' first mentioned shaft and geared thereto,spaced roller clntches carried by said second sha'ft, cranks connected to said clntches,operating pedals and fieXible connections between the pedals and cranks.

` In testimony Whereof I afiix my signature.`
